TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Feb. 14, 1911.

To all whom 'it may concern:

Be it known that I, EDWARD B. lines, a citizen of the United States of America, residing in the borough of Manhattan, city, county, and State of New York, have invented certain Improvements in Ty e-Writing Machines, of which the following is a specification.

This invention relates to the segment in which the type bars of a front strike ma- .chine are mounted and to parts associated mental passage way, seat or groove 4. The

seat 4 1s formed in manner described in the application of Philip Stern, filed August .26, 1909,-No. 514,673 upon which this invention is an improvement; that is to say there is first cut in the peripher of the segment a slot 5 of uniform depth a er which the seat 4 for the pivot wire 3 is cut of a greater width than the slot by a tool the shank of which travels in the slot. My construction differs from that of Stern in that the slots 2 are protected by the overlying solid part 6 of the segment and by the type bar abut ment 7 from dust and dirt of erasure falling either to the front or rear of the segment. In this case, the type bars 8 are formed with an enlarged pivot end 8, the rear edge of which when the bar is in printing position is in a lane considerably in rear of'that in which t e type faces lie. Secured to the segment above the abutment 7 is a usual form of type bar uide 9. The abutment 7 is segmental in s ape, projects forward from the face of the segment and is designed to receive the impact of the type bars intermediate their heads and pivots to limit or prevent undue penetration of the type faces into the paper being printed on. Fig. 3 shows the seat for the ivot wire as square in cross section. In either case, the wire which, of course, must be inserted endwise is held firmly and positively in the segment which may be made of a single piece or casting. It is for some reasons deemed advisable that the type bar abutment be made adjustable. A mode of adjustment is indicated in Figs. 4 and 5 in which the abutment 7 is a separately formed segmental piece adapted to receive two screw bolts 10, 10 working through threaded apertures in the segment. Between these two bolts is a screw stop bolt 11 and adjacent each end of the segmental abutment outside of the screw bolt 10 is a stop bolt 12. The abutment may be adjusted to bring its impact surface in a desired plane by manipulation of the adjusting and stop bolts, as is obvious.

I claim:

1. A type bar segment formed of a single piece of metal having peripheral radial slots and an overlyin solid portion protecting the slots from t e dirt of erasure, a segmental seat to receive a type bar pivot wire and a slot of less width than said seat extending therefrom to the periphery or bottom face of the segment.

2. A type bar segment having slots for the reception of the pivot ends of the ty e bars, a segmental abutment carried on t e face of the segment above the slots, adjustable screw bolts passing through the segment and engaging apertures in the abutment and cooperating adjustable stop screws. In testimony whereof, I have hereunto subscribed my name.

EDWARD B. HESS.
